Hello,
There is no relationship between SDK and MCAL.
SDK is more like simple example SW, but MCAL is fully qualified for ASIL-D standard and production.
If you are going to mass production for example in automotive then MCAL is the way which customers choose.
You can use SDK but it offers only a fragment MCAL functionality. It really depends on what are you going to develop.
For MCAL you will need also compilers validated for MCAL like GHS/windriver.
best regards,
Peter
